Unlocking Earth AI’s planetary geospatial foundation models for global public health, Google Research announced. Quick links Paper News from Google blog Share Copy link × Public health decisions rely heavily on timely, granular data. For acute disease outbreaks, such as dengue or cholera, it can help inform urgent operational protocols and resource allocation.

However, conventional epidemiological surveillance is often hindered by limitations in data: multi-year reporting lags, data siloed by rigid geopolitical boundaries, and data sparsity. Even without these limitations, traditional modeling approaches require extensive task-specific data collection and custom data engineering pipelines that are difficult to deploy during rapid outbreaks or in resource-constrained settings.

PDFM compresses privacy-preserving search trends, human mobility, built-environment density, and environmental determinants into location embeddings. Environmental determinants : High-resolution weather and air quality metrics and statistics. Prior work showed that these embeddings are task-agnostic.
